Windows only: Portable system-fixing bundle Computer Repair Utility Kit puts 57 recovery tools into a single package. That gives you easy access to important system utilities without the fuss of building your own toolkit.
The launcher can be run directly from the folder or copied to a flash drive for access from any system, with a system tray menu for quick access to the included tools—which can be tweaked to add your own favourite portable applications. Most of the included utilities are familiar to Lifehacker readers, with well-known utilities like reader favourites CCleaner and PC Decrapifier along with dozens of other utilities that perform tasks ranging from killing spyware to system tweaking—and a copy of Portable Firefox is even included for good measure. If you haven’t taken the time to build your own flash drive toolkit, this download might be worth a look to get you started. Computer Repair Utility Kit is a free download for Windows, though readers should be forewarned that some of the actual download links on the home page purposely take you to ad-ridden, pop-up crazy download sites—getting to the actual download is more than a little annoying.
